TANK-CAR Patented June 25, 1907.

Application filed Ilccember 28, 1906. Serial No. 349,878.

To all wlwm it may concern: Bejit known that I, JOHN MoE. AMEs, citizenof the United States, residing at the city, county, and State of NewYork, have invented a certain new and useful Improvement in Tank-Oars,of which the following is a full, clear, and exact description, such aswill enable others skilled in the artto which it appertains to make anduse the same, refer ence being had to the accompanying drawings, formingpart of this specification, in which Figure 1 is a side elevationalView, artly in vertical section, of my improved ta car; Fig. 2 is asectional View taken on the line 22 of Fig. 1 Fig. 3 is a plan View of aportion of the underframe, Fig. 4 illustrates a modified form ofinterlocking members between the tank and underirame; and Figs. 5 and 6illustrate a further modification.

This invention relates to new and useful improvements in tank cars.

The usual practice in tank car construction 7 is to mount the tank on anunderframe, and

to prevent the tank from rolling bands, which extend over the tank, aresecured to the underframe. To revent the tank from shifting longitudinaly,.head blocks which serve as abutments for the ends of the tank areusually secured to the underframe.

In the preferred form of my invention the tank is tied to an underframeby means of bands in the usual manner. The head blocks are replaced bylugs secured to the underframe near the center of the car, which lugsserve as abutments for a projection carried by the tank. The ad vanta eof this construction is that the tank is ree to expand and contractindependently of the underframe, as it is not connected by rivets orsimilar fastening. devices, to the underframe.

Referring to'the drawings, the underframe comprises body bolsterslocated near the ends of the car and secured to longitudinal-sills 1.Buffer blocks 2 riveted to the ends of the longlitudinal sillsare'adapted to receive suitable rawbars.

The body bolsters herein-shown are built up of flanged diaphra'gms 3which extend out- Wardly from the longitudinal sills, said diaphragmsbeing connected b a channel A arranged above the longitu 'nal sills anda plate 5 below said sills. Center bearings 6 .on thelongitudinal'sills.

are secured to the under side of the body bol sters, and filler blocks 7are interposed between the longitudinal sills above the center bearings.The tank rests on wood'blocks 8,

which blocks are secured to the curved top and a hand rail 17. A ladder18 is secured to the running board.

Flanged lates 19 are secured to the underframe, pref rably near thecenter of the car. A casting or pressed metal member 20 is secured tothe tank' and extends downwardly between the flanges of the plates 19.The member 20 is preferably provided with curved flanges which areriveted to the tank, the rivets passin through a plate 21 located insideof the ta 1. The plate 21 reinforces the tank structure at this pointand reduces the liability of leakage.

From the foregoing it will be understood that the member 20 whichprojects from the tank is held in interlocking engagement with theflanged plates 19 by means of the tank bands. However, anysuitableconnections between the tank and underframe may be emplo ed inlieu of the tank bands as the same orm no part of my invention.

Fig. 4 illustrates a modification in whicha casting provided with arecess 22 in its upper face is secured to the underframe, and one of thetank sheets is pressed out to form a proj ection 20*, which projectionis located in the recess 22.

In the modification shown in Figs. 5 and 6, a casting or pressed metalmember 20 is riveted to the bottom of the tank and rests v A portionofthe member 20" extends downwardly between lugs 19 which are riveted tothe inside oflongitudinal sills 1, Various other modifications may bemade from the design herein shown for example, a cross bearer could besecured to the longitudinal sills and lugs carried by the tank locatedon each side of said cross bearer.

I amaware that minor changes'in the-construction, arrangement andcombination of the several parts of my device canbe made andsubstitlit'ed for those herein. shown and described without in the leastdeparting I from the spirit of my invention.

Having thus described the invention, what" is claimedas new and desiredto by Letters Patent is:

1. In a tank car, the combination with a be secured tank, of a frame,and interlocking members derframe, and interlocking members form ingabutments between the tank and frame,

= which members are designed at all times to receive end thrusts andallow the tank to expand substantially throughout its length;substantially as described.

3. In a tank car, the combination with a tank, of a frame, andinterlocking members at the center of the car which prevent the tankfrom shifting longitudinally; substantially as described.

4. In a tank car, the combination with an underframe, of a. tank mountedon the undefirame, and interlocking members at the center of thecarwhich prevent the tank from shifting longitudinally; substantially asdescribed. 4

' 5. In a tank car, the combination with an underframe including bodybolsters, of a tank supported by the underframe, and interlockingmembers arranged between the body bolsters, said interlocking membersforming abutments which prevent the tank from shifting longitudinallyand allow it to expand; substantially as described.

6. In a tank car, the combination with-a tank, of an underframe, bandsanchored to the underframe and extending over the tank, and interlockingmembers which prevent the tank from shifting longitudinallyand allow itto expand, the relative position of said interlocking members beingconstant; substan tially. as described.

- 7. In a tank car, the combination with a I tank, of an underframe,bands anchored to the underframe and extending over the tank, andinterlocking members between said tank and] frame which prevent the tankfrom shifting longitudinally, the relative position of said interlockingmembers being constant;

tank, of a frame, lugs secured to said tank j and frame near the centerof the car, which lugs interlock and preventthe tank from-1'shifting'longitudinally; substantially as described.

10. In a tank car, the combination with a tank, of an underframe, lugssecured to the underframe near the center of the car, and a projectioncarried by the tank arrangedbetween said lugs; substantially asdescribed.

11. In a tank car, the combination vdth a tank,- of an underframe, lugssecured to the underframe near the center of the car, and a projectioncarried by the tank arranged between said lugs; substantially asdescribed.

12. In a tank car, the combination with a tank, of a frame includingbody bolsters, a tank-supporting membergnear the center-of the car, andlugs co-operating with said tank-supporting member to prevent. the

tank from shifting longitudinally; substantially as described.

13. In a tank car, the combination of a tank, an underframe, andinterlocking members on said tank and underframe, said members beinglocated at the center of the car and having coincident engaging faces;substantially as described.

14. In a tank car, the combination with a tank, of a frame, interlockingmembers between said tank and frame, one of which interlocking membersis riveted to'the'tank near the center thereof, the rivets passingthrough a reinforcing plate logated inside of the tank; substantially asdescribed.
